Description

[Detailed description of the invention] This invention relates to a door neck width adjustment device for fittings.

The width of sliding grooves in horizontal frames for fittings such as lintels and thresholds differs depending on the region, for example, 6-minute grooves and 7-minute grooves, so conventionally, fittings with different neck widths were used for the same type of fittings. The need arose. This was also extremely disadvantageous in terms of cost and inventory control. Therefore, as a door neck width adjustment device for fittings, a fitting part that opens on the side of the door neck is provided, and adjustment blocks with different protruding lengths are fitted into the fitting part, or adjustment is made using multiple locking grooves. Various types of devices have been devised, including those in which the locking position of the block can be selected.

However, all conventional door neck width adjustment devices only allow stepwise adjustment, and there is little room for selection of the adjustment width. Therefore, there is no way to flexibly deal with all cases, including fine adjustments.

This invention was devised in view of the above-mentioned points, and the purpose is to provide a door neck width adjustment device that is capable of stepless adjustment over a wide range of adjustment widths and that can be firmly fixed when attached to fittings. It is said that

This invention will be explained below based on illustrated embodiments.

In the embodiments shown in FIGS. 1 to 5, the device of this invention is installed on a corner block 3 as an upper sliding piece at the connecting portion between a vertical stile 1 and an upper stile 2.
The corner block 3 has fitting pieces 4a, 4b and a fitting piece 5 that fit into the vertical stile 1 and the upper stile 2, respectively, and can be slid up and down with respect to the vertical stile 1 to adjust the installation. . In this case, the width of the door neck of the fittings is given by the width of the corner block 3 in the prospective direction, and the width of the sliding groove 6 of the lintel is adjusted by adjusting the protruding length of the adjustment block 8 of the door width adjustment device. Do it by doing this.

That is, a fitting part 7 that opens on the side surface of the door neck is provided in a portion corresponding to the door neck of the corner block 3, and the adjustment block 8 is slidably fitted into this fitting part 7 and protrudes. Adjust the length. The adjustment block 8 has an adjustment screw 10 in the door neck width direction from the top side.
A locking groove 9 is formed into which the adjustment screw 10 is fitted and locked, and a screwdriver 14 or the like is inserted through the insertion hole 11 provided on the protruding end surface of the adjustment block 8 to rotate the adjustment screw 10 in the locked state. be able to.

On the other hand, the fitting portion 7 of the corner block 3 is provided with a female threaded screw hole 12 for screwing the adjustment screw 10 therein, and by operating the adjustment screw 10, the entire adjustment block 8 can be fitted. Joint part 7
It can be slid within any desired width.

In this embodiment, the insertion side of the adjustment block 8 is formed to have a U-shaped cross section, and a cutout groove 13 is provided at a predetermined position from the tip. This notch groove 1
3 is designed so that when it is desired to insert the adjustment block 8 deeper than the position where the tip on the fitting side reaches the opposing surface of the fitting part 7, the tip can be folded and removed easily. That is, the insertion side tip can be bent at the line A--A in FIG. 3.

Further, the locking groove 9 of the adjustment block 8 does not necessarily have to be provided on the top surface side, but may be provided on the side surface or the bottom surface side.

This invention has the above configuration and has the following advantages and features.

Since the adjustment screw is locked in the locking groove in the adjustment block and the adjustment block is slid in this state, the door neck width can be adjusted over a wide range in a small space.

The adjustment screw screws into the screw hole in the fitting part that opens on the side of the door neck, and stepless adjustment can be performed by rotating the adjustment screw, allowing for fine adjustment and other arbitrary adjustments, and is extremely easy to operate. It is.

The sliding direction of the fittings is different from the sliding direction of the adjustment block, and the positioning is done using adjustment screws, so it is strong and will not come off.

It is convenient to handle because it can be handled as a single component with the adjustment screw screwed in, and no other auxiliary parts are required.
